Y²+7y+10/y²-25 this is the equation now if your looking for the answer it would be
y^4+7y^3-25y^2-175y+10
_________________________
(y+5)(y-5)
sorry if is a little messy
Answer
Steps are included the distance formula is the square root of the equation (x2-x1)^2+(y2-y1)^2
your final answer is 10
So you need to multiply 64 times 12 and she has to pay $768
A negative exponent means to move the decimal point to the left the number of the exponent.
10^-1 you would move the decimal 1 place to the left.
5.401 x 10^-1 = 0.5401
